Description

  The present invention relates to a dispensing container with a pump for storing contents such as liquid food and operating the pump provided in the container mouth to dispense the contents.

  A tube may be inserted into the stomach, and liquid food such as nutrients may be injected directly into the body through the tube. Conventionally, a resin container made of a pouch or the like is known as a container for injecting liquid food in this manner. The liquid food is stored in the container, and the container is suspended at a position higher than the patient. It was poured out of the container by its own weight and sent into the stomach.

  There is also known an example in which an electric pump is connected to a tube, the liquid food is sucked up from the container containing the liquid food by an electric pump, and is fed into the patient's body.

  Furthermore, it is also considered that a hand-poured dispensing pump is assembled at the mouth of the storage container, the liquid food is stored in the dispensing container, and the liquid food is discharged by pressing the head of the extraction pump.

JP 2003-126217 A

  The pouch container is a one-time-use container, and therefore the container could not be used repeatedly. Moreover, in the container made from a pouch, the contents could not be replenished in the container, or the components of the liquid food could not be changed according to the state.

  When an electric pump is used, there is a problem that a power source is required nearby and the apparatus becomes large.

  In the case of a dispensing container in which a manual pump is assembled to the container body, there are the following problems.

  Conventionally, a pump-equipped container has a small inner diameter, and it has been difficult to inject liquid food into the container. Also, when making liquid food by adding water to powder of liquid food, it was difficult to stir the powder and water inside the container if the mouth of the container was narrow. Moreover, it took time and effort to agitate the powder and water in a container other than the container with the pump and transfer the adjusted liquid food to the container with the pump.

  Furthermore, the conventional container with a pump was not a structure which can decompose | disassemble a pump easily. Therefore, after use, the pump was operated to suck up hot water, etc., and the hot water and water were discharged from the spout to clean the contents remaining in the pump, but the inside of the pump, especially inside the cylinder, around the piston, It was difficult to completely clean the entire passage to the spout and remove the contents.

  In addition, when liquid food is poured out, the liquid food may be dried or oxidized by the air that has flowed into the container instead of the poured liquid food.

  An object of the present invention is to provide a dispensing container with a pump that can be easily stirred inside the container and injected with contents, and that can reliably clean the inside of the container, particularly the inside of the pump and the inside of the container.

  In order to solve the above-mentioned problem, the present invention comprises a container body having a mouth part at the upper part and a pump assembled to the mouth part, and a dispensing container for dispensing the contents from the container body by pressing the head of the pump. Was configured as follows.

  The container body is a cylindrical wide-mouthed container whose mouth is formed to have the same diameter as that of the body of the container body. Further, an inner pan is placed inside the container body, and the container body is liquid-tight on the inner surface of the container body. It was provided to be movable in the vertical direction.

  The pump can be disassembled.

Specifically, the pump includes a head having a spout, a pipe that communicates with the spout and extends downward, and a lid that is slidably assembled and detachably attached to the mouth. A disc-shaped piston that is movably assembled to the lower part of the tube, a cylinder chamber that communicates with the inside of the container body via a suction valve, and the piston is slidably assembled inside, and a head is attached upward. With a spring
Furthermore, the lid is formed so as to be detachable by screwing into the upper lid assembled with the tube and the lower lid having the cylinder, an introduction hole leading to the inside of the tube is provided on the lower side surface of the tube, and the head is When positioned above, the assembly base of the piston assembled on the outer peripheral surface of the tube closes the introduction hole, and when the head is pressed down, the assembly base moves above the tube and the introduction hole opens. And the stopper which closes the lower end of a pipe body was provided in the lower end of the pipe body so that attachment or detachment was possible, and the extraction container was constituted.

  A cylindrical piston guide is attached to the lower inner surface of the tube so that it protrudes from the lower end of the tube, an introduction hole is formed in the side of the piston guide, and a stopper is detachably attached to the lower end of the piston guide. The assembling base was assembled to the outer peripheral surface of the piston guide, and the piston was movably held between the lower end of the tube body and the lower end of the piston guide to constitute a dispensing container.

  The dispensing container of the present invention has the following features.

  When the head of the pump is pressed, the piston is pressed in the cylinder, and at the same time, the introduction hole is opened, and the contents that have passed through the introduction hole rise through the tube and are poured out from the spout. A tube inserted into the stomach is connected to the spout, and contents such as liquid food are fed into the patient's stomach through the tube. Since the dispensing container has a wide piston pressing surface, it is possible to feed out a sufficient amount of contents only by pressing the head once.

  When the head pressing operation is stopped and the head is lifted by the spring, the introduction hole is closed by the piston assembly base, so that negative pressure is generated in the cylinder, and the inflow valve is opened by the negative pressure, and the inflow valve is opened in the cylinder. The contents flow from inside the container body. Thereby, when the head is next pressed, the contents are immediately poured out.

  The opening and closing of the inside of the tube body and the inside of the cylinder can be controlled by a simple structure of the introduction hole formed in the tube body and the assembly base portion of the piston.

  Further, when the contents flow into the cylinder, the inner tray moves up as the contents decrease. Thus, even if the contents are poured out, air does not flow into the container body, and the contents do not touch the air.

  By disassembling the lid of the pump into an upper lid and a lower lid, the piston can be removed from the cylinder, and the inside of the cylinder and the piston can be cleaned directly. Furthermore, the plug body can be removed from the lower end of the pipe body, and tap water can be allowed to flow into the pipe body, or a bellows-like dropper can be connected to the lower part of the pipe body, and washing water can be pushed into the pipette easily and reliably. The entire interior of the tube can be cleaned.

  Since the container body has a wide mouth, it is easy to put the contents into it and it is easy to handle. In addition, it is possible to easily adjust the predetermined liquid food by adding water to the liquid food powder in the container body and stirring the mixture, or by appropriately adding auxiliary agents of different components. Therefore, it is not necessary to make a liquid food in a separate container, and it does not take time. Furthermore, since the container main body has a wide mouth and the inner dish can be pushed down easily, the inside of the container main body can be cleaned easily and reliably.

  An embodiment of the dispensing container of the present invention will be described with reference to the drawings.

  The dispensing container 1 is a resin-made dispensing container, which is composed of a pump 2 and a container body 4 as shown in FIG. 5, and a lid 6 of the pump 2 as shown in FIG. 4. It is screwed to the mouth portion 8 and assembled together. In the dispensing container 1, for example, a tube 60 is attached to the spout 10 of the pump 2, the tip of the tube 60 is inserted into the stomach of a human body (not shown), and the pump 2 is operated to store contents such as liquid food. Used to send out.

  The pump 2 includes a head 14, a lid 6, a piston 18, a cylinder 20, and the like. The head 14 includes a spout 10 that extends laterally and a tubular body 16 that extends downward, and is integrally formed of resin. The tube body 16 communicates with the spout 10 inside, and is slidably assembled in an attachment hole 28 formed in the center of the lid body 6. A sliding cylinder 15 is provided concentrically with the tube 16 below the head 14.

  The lid body 6 is composed of a resin upper lid 24 and a lower lid 26, and is assembled so as to be removable by screw fitting. Thus, the pump 2 can be divided into an upper half 3 including the upper lid 24 shown in FIG. 1 and a lower half 5 including the lower lid 26 shown in FIG.

  As shown in FIG. 1, the upper lid 24 has an internal thread 25 on the inner surface, and a mounting hole 28 to which the tube body 16 is assembled is formed at the center of the top plate 7. A cylindrical guide cylinder 17 is formed concentrically with the mounting hole 28 on the top surface of the top plate 7. The guide cylinder 17 is slidably assembled with a slide cylinder 15 provided below the head 14. A coiled spring 22 is attached to the circumferential gap between the tube 16 and the guide cylinder 17, and the head 14 is always urged upward by the spring 22.

  A holding cylinder 30 having the same diameter as the attachment hole 28 is formed on the lower surface of the top plate 7, and the tube body 16 is slidably fitted to the holding cylinder 30.

  The pipe body 16 is formed so that the inner diameter is two steps wide at the lower portion, and a piston guide 32 is integrally fixed inside the first step.

  The piston guide 32 is a cylindrical resin member. A male screw 33 is formed on the outer periphery of the lower end, a flange 36 is provided on the upper part of the male screw 33, and an introduction hole 38 is formed above the flange 36. The piston guide 32 is formed to have the same inner diameter as the inner diameter of the pipe body 16 so that the inside is continuous with the inside of the pipe body 16.

  A plug 34 can be removably attached to the male screw 33 by screw fitting. When the plug 34 is attached as shown in FIG. 4, the lower end of the piston guide 32 is sealed.

  The flange 36 has a circumferential groove 37 on the upper surface. A lower end of an assembly base portion 19 of the piston 18 described later is fitted into the groove 37 in a liquid-tight manner. The introduction hole 38 is formed in at least one place on the side wall of the piston guide 32, and communicates the inside and the outside of the piston guide 32.

  The piston 18 is a resin member having moderate elasticity, and includes a disk-shaped substrate 21, an assembly base portion 19 provided on the inner side of the substrate 21, and an annular sealing material 23 provided on the outer peripheral edge of the substrate 21. Is formed. The assembly base 19 has a cylindrical shape, and a lower end is assembled to the inside of the groove 37 so as to be detachable, and an upper portion opens outwardly, and comes into liquid-tight contact with the second stage inner surface of the tube body 16.

  The upper surface of the substrate 21 is separated from the lower end of the tubular body 16 by a predetermined distance in a state where the lower end of the assembly base portion 19 is accommodated in the groove 37. As a result, the piston 18 can move in the axial direction of the piston guide 32 from the state in which the lower end of the assembly base 19 is accommodated in the groove 37 until the lower end of the tube body 16 contacts the upper surface of the substrate 21. ing.

  The annular seal member 23 has an outer diameter substantially equal to the inner diameter of the cylinder 20, and when the upper lid 24 and the lower lid 26 are assembled, the outer peripheral surface of the annular seal member 23 is slidably in close contact with the inner surface of the cylinder 20.

  As shown in FIG. 2, the lower lid 26 includes a male screw 41 and a female screw 43 on the outer periphery, and the cylinder 20 is attached to the center.

  The male screw 41 meshes with the female screw 25 of the upper lid 24, and the female screw 43 is formed so as to mesh with a male screw 51 (see FIG. 3) formed on the outer periphery of the mouth portion 8 of the container body 4.

  The cylinder 20 includes a cylindrical cylinder wall 44 and a bottom plate 42, and an inflow hole 45 and a valve 46 are provided in the bottom plate 42. The valve 46 is attached to the upper surface of the bottom plate 42 and opens the inflow hole 45 from the outside to the inside of the cylinder 20.

  The container body 4 is composed of a resin barrel 52, a bottom plate 56 attached to the lower portion of the barrel 52, and an inner tray 54 assembled in the barrel 52, as shown in FIG. This is a wide-mouthed container with little change in diameter from the mouth 8 to the bottom plate 56.

  On the outer periphery of the mouth portion 8, a male screw 51 that meshes with the female screw 43 is formed.

  The intermediate tray 54 is made of a resin having moderate elasticity, and is slidably in close contact with the inner surface of the barrel portion 52, and can move up and down while maintaining liquid tightness in the axial direction of the container body 4.

  The bottom plate 56 is disc-shaped, has a hole 58 communicating with the inside of the body portion 52 at the center, and is fixedly attached to or removed from the lower portion of the body portion 52.

  Next, the operation of pouring liquid food using the dispensing container 1 and the operation of each part in the dispensing container 1 will be described.

  First, the middle tray 54 is moved to the bottom of the container body 4, and the liquid food is put into the container body 4. The liquid food can be prepared directly from a bag or the like into the container body 4 or by adding powder and water or hot water into the container body 4 and stirring. May be adjusted as appropriate.

  The pump 2 is assembled to the mouth 8 and the tube 60 is connected to the spout 10. The head 14 is pressed a plurality of times, the air in the container body 4 is pushed out, and when the liquid food starts flowing through the tube 60, the tip of the tube 60 is inserted into a predetermined place.

  The operation of each part in the dispensing container 1 when the head 14 is pressed will be specifically described.

  FIG. 4 shows the dispensing container 1 before the head 14 is pressed. In this state, the head 14 is disposed above by the bias of the spring 22. For this reason, the pipe body 16 is pulled up, the assembly base 19 is fitted in the groove 37, and the lower end of the holding cylinder 30 is in contact with the upper surface of the assembly base 19, so that the introduction hole 38 is closed. .

  When the head portion 14 is pressed against the spring 22, the tube body 16 is pushed down into the lid body 6. When the pipe body 16 is pushed down, the piston guide 32 is also pushed down. However, since there is a gap between the lower end of the tube 16 and the substrate 21 of the piston 18, the piston 18 does not move until the lower end of the tube 16 contacts the substrate 21. Therefore, the lower end of the assembly base portion 19 is separated from the groove 37, a space is formed between the lower end of the assembly base portion 19 and the flange 36, and the introduction hole 38 is opened.

  On the other hand, since the piston 18 is pushed down, the internal pressure of the cylinder 20 rises and the inflow hole 45 is closed by the valve 46.

  Accordingly, when the head 14 is pressed, the liquid food stored in the cylinder 20 flows into the tube body 16 through the opened introduction hole 38 and is poured out from the spout 10 into the tube 60.

  When the hand is released from the head 14 and the pressing is stopped, the head 14 is pushed up by the spring 22. When the pipe body 16 is pushed up, the piston guide 32 moves upward, the lower end of the assembly base 19 is fitted into the groove 37, and the upper part of the assembly base 19 is in contact with the inner surface of the piston guide 32, so that the introduction hole 38 is closed. At the same time, the piston 18 is pushed up by the piston guide 32 and a negative pressure is generated inside the cylinder 20, so that the valve 46 opens the inflow hole 45 and the liquid food in the container body 4 flows into the cylinder 20.

  Further, when the liquid food flows from the container main body 4 into the cylinder 20 and the liquid food stored in the container main body 4 decreases, the intermediate plate 54 is sequentially pulled up. When all of the liquid food stored in the dispensing container 1 is poured out, the intermediate dish 54 moves to the position indicated by the two-dot chain line in FIG.

  Next, a procedure for disassembling and cleaning the dispensing container 1 from which the liquid food has been poured out will be described.

  First, the pump 2 is removed from the container body 4 by rotating between the female screw 43 and the male screw 51. The removed container body 4 cleans the inside by pushing down the inner tray 54.

  The pump 2 rotates between the female screw 25 and the male screw 41 to divide the upper lid 24 and the lower lid 26. When the upper lid 24 and the lower lid 26 are divided, the piston 18 is taken out from the cylinder 20, and each is washed. Further, the stopper 34 is removed from the lower portion of the piston guide 32 and the inside of the tube body 16 is washed from the lower end of the piston guide 32. The inside of the pipe body 16 can be washed by directly flowing tap water into the piston guide 32, or a bellows-like dropper is attached to the lower end of the piston guide 32, and the cleaning liquid put in the dropper is sent into the pipe body 16 You may wash in this way.

  As a result, it is possible to surely clean all the parts that have been difficult to clean in the past, such as the inside of the container body 4, the inside of the cylinder 20, the outer surface of the piston 18, and the inside of the tube body 16, and the contents easily remain.

  After the cleaning, the upper lid 24 and the lower lid 26 are assembled, the liquid food is introduced into the container main body 4, and the pump 2 is assembled into the container main body 4, whereby the dispensing container 1 can be reused any number of times. .

  In addition, the extraction container 1 can be used not only as a container for discharging liquid food but also for other uses.
